According to experts, people who smoke cigarettes are pumping out ten times more toxic air than cars. (24 August 2004, BBC News). Dr. Giovanni Invernizzi and his team from the tobacco control unit in Milan experimented in a controlled environment in a small town in Italy. They found that the toxic particulate matter of cigarettes is ten times more than diesel engines. We, as human beings, should be more responsible, but we are not. Can you imagine we are more dangerous than engines for this nature and society?
